{"id":"CVE-2023-52834","summary":"atl1c: Work around the DMA RX overflow issue","details":"In the Linux kernel, the following vulnerability has been resolved:\n\natl1c: Work around the DMA RX overflow issue\n\nThis is based on alx driver commit 881d0327db37 (\"net: alx: Work around\nthe DMA RX overflow issue\").\n\nThe alx and atl1c drivers had RX overflow error which was why a custom\nallocator was created to avoid certain addresses. The simpler workaround\nthen created for alx driver, but not for atl1c due to lack of tester.\n\nInstead of using a custom allocator, check the allocated skb address and\nuse skb_reserve() to move away from problematic 0x...fc0 address.\n\nTested on AR8131 on Acer 4540.","modified":"2026-04-02T09:43:22.959370Z","published":"2024-05-21T15:31:35.575Z","related":["ALSA-2024:5102","SUSE-SU-2024:2008-1","SUSE-SU-2024:2011-1","SUSE-SU-2024:2019-1","SUSE-SU-2024:2189-1","SUSE-SU-2024:2190-1","SUSE-SU-2024:2360-1","SUSE-SU-2024:2381-1","SUSE-SU-2024:2561-1","SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52834.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/32f08b7b430ee01ec47d730f961a3306c1c7b6fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/54a6152da4993ec8e4b53dc3cf577f5a2c829afa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/57e44ff9c2c9747b2b1a53556810b0e5192655d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/86565682e9053e5deb128193ea9e88531bbae9cf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c29a89b23f67ee592f4dee61f9d7efbf86d60315"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52834.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52834"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"43250ddd75a35d1f7926d989a10fefd30c37eaa7"},{"fixed":"c29a89b23f67ee592f4dee61f9d7efbf86d60315"},{"fixed":"57e44ff9c2c9747b2b1a53556810b0e5192655d6"},{"fixed":"54a6152da4993ec8e4b53dc3cf577f5a2c829afa"},{"fixed":"32f08b7b430ee01ec47d730f961a3306c1c7b6fb"},{"fixed":"86565682e9053e5deb128193ea9e88531bbae9cf"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-52834.json"}}],"schema_version":"1.7.5"}
